Has anyone else been experiencing Bluetooth and other audio problems with the most recent firmware update? My wife and I own an S and an X - experiencing same very frustrating problems in both vehicles. Bluetooth connectivity to phone is intermittent, volume is low, Nav voice comes back on even though it has been previously muted. Extremely frustrating. Have called in several times, Tesla says they haven't heard any other concerns and to just wait for the next update. We just can't understand how we are experiencing the same exact problem in two different Tesla vehicles with two different phones. We've owned Tesla vehicles since 2014 and this is unlike anything we have ever experienced. Not happy.
